The song is “Hold On” by Chord Overstreet. It’s about someone pleading with their lover, who attempted suicide, to pull through and not die. I find it incredibly difficult to perceive Chloe’s self-flagellating “I don’t deserve to live” speech in Episode 5 as anything other than a suicidal crisis. I think her offer to be sacrificed was mostly a result of her depression and feelings of low self-esteem and hopelessness. It would be deeply wrong for Max to take Chloe up on her offer. It would be no different than letting Kate jump, just because she wanted to when she was on the roof. In Season 1 Chloe is depressed and I mean in the medical sense. Max can find prescription antidepressants in Chloe’s bathroom. Sweet innocent Max, not knowing what Fluoxetine is, comments the find with “Chloe is taking medicine? I hope she’s okay”, as if those were vitamins, but it’s actually a potent antidepressant. This is also the reason Chloe craves weed - for its antidepressant properties (that’s the whole reason medical marijuana is even a thing). Notice that Chloe starts blazing when she’s feeling down, like when she’s with Max in her room in Episode 1. Chloe most likely had suicidal thoughts prior to meeting Rachel. I don’t know how else you can explain her standing in front of speeding trains. And she said Rachel had “saved” her, which implies she would’ve done something very bad hadn’t it been for her friendship with Rachel. The thoughts came back after Rachel’s disappearance. In Chloe’s hideout at the junkyard, Max can find a scribbled note which says “I want to die”. Max wonders aloud who wrote this, but at that point, Chloe has been the only one using the hideout for months. And the note is in all capital letters, just like “Chloe was here” on the wall, in contrast to Rachel’s and Max’s signatures. Chloe tragically lost her father. Her mother moved on way too quickly, hiding her late husband’s photos and refusing to acknowledge Chloe’s grief. Her only friend left and cut contact. She was bullied at school for being a “scholarship kid”. Rachel promised her a life together but then decided to skip town with someone else. Her stepfather made her feel worthless (can you even imagine hearing from your own parent that you’re a loser and that others should stay away from, because you would only drag them down?). Frank hooked her up on drugs when she was still a minor and when she couldn’t pay her debt he exploited her as an accomplice to his crimes and then started threatening to cut her. Nathan slipped her date rape drugs and attempted to assault her, which she barely avoided. And then, in the span of four days, she was almost killed multiple times and she found Rachel’s decayed corpse. It would be weirder if after all that she didn’t want to die. Someone who went through all that cannot make a fully informed, conscious decision to be “sacrificed”. If Max fought tooth and nail to save Kate, who was driven to suicide by all the bad things that happened to her, wouldn’t she do the same for Chloe?
